Abstract
There are provided a developer management method, a developer management device, a plate-making method, and a plate-making apparatus that can prevent development residues from being adhered, can perform appropriate development, and decrease the replacement frequency of a developer. A plate-making method has a developing step of removing and developing a non-exposed portion of an imagewise exposed flexographic printing plate precursor using a developer, a measuring step of measuring a conductivity of the developer used in removing the non-exposed portion of the imagewise exposed flexographic printing plate precursor, and a replenishing step of replenishing at least one liquid of a development replenishing liquid or water to the developer based on the conductivity measured in the measuring step such that the conductivity becomes a conductivity in a determined range.
